The weapons I have chosen to hunt with and to protect my family with were chosen because they are the best tools for the job at hand. My job might be different than your job and my living circumstances might be different.

An AR is an example of a lightly recoiling weapon that is capable of being adjusted to fit a myriad of shooters and is realitivly easy to place consistent hits on target with.

If you live in a home where a variety of family members may need to use the same weapon to defend the family and the home not many better options come to mind.
